Impact of INM on Selected Mulberry and Silkworm Traits

The Study was carried out during the years 2016 -2018 under bore well irrigated condition at Doddamudugere village, Talavady area to study the effect of Integrated Nutrient Management (INM) in Mulberry and it is effect on Physico-Chemico properties of Silkworm, V-1 Mulberry variety planted at 3 * 3 spacing. Two INM Combination were tested against recommended dose and control, data recorded with three different time interval, Leaf quality assessed via fed to Silkworm. Significantly increased plant growth parameters were recorded in Treatment - T3, Replication R3 (time gap) such as Plant height (171.1cm), Number of shoots plant 1 (9.7) Number of leaves plant 1 ( 368.2) and leaf yield plant 1 (1680.3 g) over T1, T2, control, under INM combined with 3 MT Vermi-compost ac 1 yr 1 with 12 liters of Panchagavya@3 % level ac 1 yr 1 Bivoltine CSR2 X CSR4, Larvae fed with Treatment T3, R3, showed significantly higher in physic-chemico properties of Silkworm, such as Cocoon weight (2g), Shell weight (0.51g), Shell ratio (25.5 %) and larval weight (4.4g), pupal weight (1.52g) observed high in T3, R2 than PM * CSR2 X CSR4. In this experiment, both plant growth parameters and bioassay showed superiority of INM practiced over control and recommended package of practices.
